The early Fastnets saw a high proportion of yachts failing to complete the course. This was mainly due to the toughness of the course, inexperienced crews, old, slow and ill-equipped yachts and the traditional designs of the British yachts lagged behind their fellow competitors from across the pond. Bad weather was also a dominant factor and the 1931 Fastnet saw gale force conditions and many problems for participating yachts, with one person being lost overboard. The tragedy marred what otherwise would have been a classic Fastnet, as the four leading yachts raced the last miles in close company and finished within minutes of one another.
The 1965 Admiral's Cup had also attracted teams from Sweden, Holland, France and the US. Irish and Australian teams also took part as relative newcomers. In 1967 the Australians took the Admiral's Cup trophy back to Sydney showing they were now in the same league as the Americans and Europeans.
